Physiology in DM Medicine
DM Medicine is not only about Diseases and Clinical Cases. We know students concentrate more on applied aspects.
From our experience of last 5 years questions be it CBT Based tests or earlier Paper and pen based Exams, we have seen that students font get most questions right. Faulty study practice to blame. Students expect in NEET SS especially NEET DM mostly questions based on diseases.
Important in NEET SS exams are the Basic Concepts. In medicine a fundamental knowledge of your Physiology is important.More so in DM General Medicine.
Subject specific questions based on Physiology are in high percentage.
Example in Cardiology you don’t expect only questions based on VSD, ASD, Mitral stenosis, A bulk of Questions are asked on Cardiac Index, Cardiac Cycle, Dynamics and Features of Cardiac Muscle, JVP tracings , Basics of Pressures.
Similarly in DM Neurology expect Questions on Cerebral Blood Flow, Autoregulations, CSF Pressures, Cerebral metabolism, Physiology of Neurons.
Below are some Examples based on Types of Basic Questions asked in NEET DM . They would seem to be questions similar to NEET PG but mostly NEET SS Students get them wrong.
Dopamine acts through
- a) Single pass receptor
- b) Four pass receptor
- c) Seven pass receptor
- d) Ligand gated channel
Which of the following favours filtration at the arteriolar end of the capillary bed.
- a) Decrease in hydrostatic pressure of capillaries
- b) Increase in hydrostatic pressure of capillaries
- c) Increase in oncotic pressure of capillaries
- d) Decrease in oncotic pressure of interstitium
Vanilloid receptors are activated by:
- a) Pain
- b) Vibration
- c) Touch
- d) Pressure
The main difference between REM sleep and wakefulness is:
- a) EEG desynchronization
- b) Rapid eye movements
- c) Decreased muscle tone
- d) Penile erection
On electromyography, all of the following features suggest deneravation, except:
- a) Unregulated firing of individual muscle fibres
- b) Small short-duration polyphasic action potentials
- c) Presence of positive sharp waves
- d) Spontaneous firing of motor units
Group A nerve fibers are most susceptible to:
- a) Pressure
- b) Hypoxia
- c) Local anesthetics
- d) Temperature
Which of the following conditions lead to tissue hypoxia without alteration of oxygen content of blood?
- a) CO poisoning
- b) Met Hb
- c) Cyanide poisoning
- d) Respiratory acidosis
Try to Attempt them. Now assess your confidence in answering such questions. Some of you will surely have a bit of difficulty in answering such questions. That’s the truth.
So reassess and review your preparation. Medexams anticipates the difficulty of students. That’s a very important feature to be taken note of. It is imperative for a student to know what is asked. Most students fall into the trap of revising only Clinical Cases and Diseases. Fundamentals are important. Don’t underestimate the Basic Physiology in preparation of your Neet DM.
